Summary

The Network Time Protocol (NTP) is used to synchronize a computer's

time with another reference time source. This package includes ntpd

(a daemon which continuously adjusts system time) and utilities used

to query and configure the ntpd daemon.

Perl scripts are in the ntp-perl package, ntpdate is in the ntpdate

package and sntp is in the sntp package. The documentation in HTML

format is in the ntp-doc package.
